Most, if not All, Asian houses have Grille Doors and with it Padlocks to secure them. Add value to this, use a Combination Padlock instead of a Keyed one.
Why? When handbags are snatched, more often than not, the house keys AND address, by way of the Identity Card, are available to the criminals. Whilst the victim is busy making a Police Report, the criminals will be busy ransacking her house. A combination padlock will stump them.
As for the Guys, should you lose your house keys, you needn’t have to rush back to change all the front door locks. That is, if you realise your loss before someone has gained entry into your house. Cheers!
